Vaughn De Leath (September 26, 1894 – May 28, 1943) was an American female singer who gained popularity in the 1920s, earning the sobriquets "The Original Radio Girl" and the "First Lady of Radio." Although very popular in the 1920s, De Leath is obscure in modern times.
De Leath was an early exponent of a style of vocalizing known as crooning. One of her hit songs, "Are You Lonesome Tonight?," recorded in 1927, achieved fame when it became a hit for Elvis Presley in 1960.
